We use JD Power data at work, it's a pretty well respected resource. As you say, it doesn't account for the severity of the issue, but to most buyers that is irrelevant, as everything is under guarantee. They don't care if it's a 1 hour fix or 2 days, a fault is a fault if it has to go back to the dealer.
